摘要： A maintenance support system includes a numerical controller that controls the drive of an operating mechanism of an industrial machine and a server that is a support device capable of communicating with the numerical controller, and the maintenance support system supports maintenance of the industrial machine. The numerical controller includes a first information generating unit that acquires, from among data related to a state of operation of the operating mechanism, data related to the state of operation of the operating mechanism when an anomaly is found in an operation of the operating mechanism, and generates first information including the data acquired. The server includes a second information generating unit that generates second information to be proposed to the numerical controller for the maintenance on the basis of the content of the first information.

摘要： A method for a device to monitor performance of a manufacturing machine which is equipped with a fixture for holding a workpiece, the fixture having at least one fixing hole, includes obtaining actual coordinate values of the fixing hole in a plurality of machining processes and calculating a standard deviation of the coordinates in at least one axial direction according to the actual coordinate values and a preset standard coordinate value. A risk index in at least one axial direction is calculated according to the standard deviation and a preset tolerance and a determination made as to whether risk index exceeds a preset threshold. A warning is sent to the machine and supervising engineer if the risk exceeds the preset threshold. A machine monitoring device and a computer readable storage medium are also provided.

摘要： A machine or autonomous system includes a diagnostic controller and is configured to perform a method for monitoring health of a machine. The method includes monitoring a set of first electrical signals indicative of control of a motor of the machine while the machine is operated in a first autonomous mode, determining that an abnormal operating condition has occurred in response to the set of first electrical signals meeting a first criteria, having the machine operate in a test mode in response to the determination that the abnormal operating condition has occurred, monitoring a set of second electrical signals indicative of control of the motor during the test mode, and determining a fault condition in response to the set of second electrical signals meeting a second criteria.

摘要： A method for generating a quote for fabrication of a part to be fabricated includes receiving, from a customer device associated with a customer, a design request for a part to be fabricated by a fabrication process, the design request including a two-dimensional drawing file representing the part to be fabricated and descriptive information including a descriptive datum. The method includes extracting a first feature from the 2D drawing file, wherein the first feature represents a geometry of the part to be fabricated. The method includes extracting a second feature from the descriptive information, wherein the second feature represents the descriptive datum. The method includes generating, as a function of the first and second features, a quote for fabrication for the part to be fabricated, the quote for fabrication including a cost and time to fabricate the part to be fabricated and sending the quote for fabrication to the customer.

摘要： A numerical control system diagnoses and maintains a numerical control machine tool by measuring backlash and downloading a backlash correction value to the numerical control machine tool. The system includes a host computer device that downloads a monitor management program to a numerical controller of the numerical control machine tool, collects numerical control information input/output between the numerical controller and a servomotor, analyzes the numerical control information, and diagnoses the numerical control machine tool.
